Annihilation of positrons, emitted at β+-decay with electrons of the daughter's atom

The processes of photon creation or atom ionization during annihilation of positron with other electron of daughter’s atom at β+-decay are considered. The estimations for the probability of one photon annihilation emitted in the process β+-decay of positron with K-electron of daughter’s atom are obtained. Process of atomic shell ionization during annihi-lation of positron, emitted at β+-decay, with K-electron of daughter’s atom is considered. Ratio of probabilities of these processes to the probability of ordinary β+-decay is found.
